GMAT preparation strategies:

Understand the content and question types for each section (Quantitative, Verbal, Integrated Reasoning, and Analytical Writing).
Start your preparation early to allow sufficient time for learning and practice.
Utilize a mix of study materials, including GMAT prep books, online resources, and official practice tests.
Set specific goals and track your progress throughout the preparation period.
Practice regularly and aim for a balance between learning new concepts and reviewing previously covered material.
Seek help or tutoring if you encounter difficulties in understanding certain topics.
Focus on understanding the underlying concepts rather than memorizing answers.
